The thermostat is located where the upper radiator hose connects to the engine.

Heater doesn't work, overheating engine, anti-freeze waisting fast??

The problem possibly could be due to a hole in the coolant system, i.e. a hole in a radiator hose or even the radiator. Loss of coolant will cause the heater to stop working and the engine to overheat. If it runs normally for a time, such as several days or a few weeks, and only after that time has passed the heater stops working and the engine starts overheating, then suspect a leak someplace. If it starts overheating after driving 5 to 10 minutes regardless of how recently antifreeze was added then, possibly the thermostat. It is staying stuck shut and preventing the hot coolant from leaving the engine and cooling in the radiator. The radiator overflow will probably have antifreeze pushing out the cover as a clue. However this can also be the result of a blown head gasket. As far as the fan, does the vehicle have an electric fan or is it driven directly by the drive belt. If it's electric, then warm it up to operating temp and open the hood and listen if the fan runs or not. It will start and stop depending on how warm the engine antifreeze is. If it does run, then the fan is fine, if not then the temp sensor that activates it is not working and needs to be replaced, or the plug into the fan may have become disconnected. If it's driven by the drive belt, then it should not be an issue unless the belt is broken, which would probably be affecting the power steering and alternator as well. If the vehicle has no power steering and the alternator light is on when running and it overheats, check to see if the drive belt is broken/missing. Check also to see if the water pump pulley is wobbly or loose. That would indicate a bad pump and would need to be replaced. Hopefully you just have a hole in a hose, and a simple hose replacement will fix it. incidentally, it's a good idea to replace both upper and lower radiator hoses at the same time, and the upper radiator hose is usually attached to the thermostat housing, so replace the thermostat at the same time too. Good luck.

1997 ford expedition overheating problem truck warms up fine heat works good then heat goes cold and temp gauge jumps from normal to overheating i have changed the thermostat twice water pump fan clutch...

This might sound like too simple a solution, but after owning 5 expeditions, I think I may have an idea.

It is possible that the cooling system is simply not full of fluid. If, when changing the thermostat twice and other service, the system was not sufficiently bled or burped, this can happen. What happens is that people do these repairs, and then fill the radiator, but fail to completely flush the cooling system. My son had the exact same problem on his Mazda 3 (Mazda was owned by Ford then), and flushing his cooling system solved his problem.

Think of it this way: If your heater works fine, then goes cold, that usually means the heater coils which the air blows over have no hot fluid in them. As for overheating, your thermostat opens when your engine reaches a certain temperature with the intent to exchange the too-hot fluid with water cooled by the radiator, but if there is only air, or insufficient fluid in the engine after the exchange, you will overheat.

Ask your mechanic to flush/burp the cooling system completely. I hope this works.

Need to know where the fan motor and resistor is located on the 2003 Ford Focus. Car overheats while idling, driving, in park, and it'll still overheat when the heater is on. Tell me what site I can find...

Cars usually overheat when the thermostat is faulty, coolant level is low, or the water pump fails. If your cooling fan on the radiator does not kick on shortly after the engine reaches operating temperature, you may have a bad cooling fan, cooling fan relay, or cooling fan fuse. If your engine is overheating, start by checking the fluid level, and installing a new thermostat.

A blower motor resistor is the device that controls a car's cabin heating and air conditioning unit's fan speeds. This usually won't cause the engine to overheat, your A/C fan may not function or only function at one speed. Here is a Blower Motor Resistor from Autozone:

I have a 2004 volkswagen jetta1.8 turbo . I replaced the 2 water pumps, and when i have the car in park after a couple of minutes it starts to overheat what might the problem be?

Make sure the fan is working. When it starts to overheat, the fans should be on. Fan failure is common. It could also be the thermostat, which is located under a black plastic piece on the bottom front of the engine. The thermostat is easier to replace, 2 10mm bolts.

2004 4.0 overheats. Replaced thermostat. No help. What is next?

The next step would be to verify the automatic cooling fan is coming on and functions when the temp rises in the engine. You may also want to check or have someone check the radiator's flow, it may be clogged.

Here are a few things to try. Check your Radiator cap pressure as a weak cap will boil over more quickly. Replace your Temperature sending unit. There may be 2, one is for the dash gauge and the other is for engine control. Unless you have other signs of overheating you may not be overheating at all, just a bad sender.

Next, the cooling fan clutch is what the fan blade is mounted on. This is checked by using a Timing light with a RPM tach made into it. The fan clutch "locks" at a variable temperature. In cold weather it slips internally. In hot weather it engages or "locks". A mechanic measures the RPM of the blade to the RPM of the engine. This tells if the fan clutch is slipping too much internally.

Before considering a new water pump try a free scan at Autozone or Oreillys. If your Catalytic converters are plugged the engine will overheat. You should have a Code for this problem in the onboard computer. About all you can try after this is to remove the Thermostat completely and see if the engine still overheats.

You will have to replace the New Thermostat again because the other engine controls will not work right without it. But without the thermostat you can test for collapsed Radiator hoses at say 2500RPM or above. Thats about all I can think of, the water pump would cost the most. The cap, sensor-sender, fan clutch, and hoses are not that expensive.

My 2004 TrailBlazer overheats in running only I changed acdelco water pump , thermostat and coolant water and still overheat

check your fan clutch, very typical problem on these 4.2L engines. These fan clutches are electronically controlled. Another issue may be clogged radiator.

1998 ford expedition 4.6 engine without tow package...overheating

If you're running it without a thermostat it's clear there isn't enough/any coolant circulating through the block. When the motor is running are the hoses off the radiator soft and flexible or stiff. If they're soft there's no coolant flowing through them. Chances are the radiator core is bad or there is a crack in it somewhere. Have it removed and tested.

2004 Jeep wrangler 4.0 - 6cyl overheating

I had the same overheating problem in my jeep ! My problem was finaly found out to be the clutch in my fan its a different kind of clutch system it work as this. When your jeep gets warmer the tighter your fan clutch gets .While cool your fan moves slowly. now to test your clutch just warm up your jeep and rev it up a bit if your fan dose not pick up speed then it is sliping.What will come out of this is that you fan will the seez and run full all the time. if you jeep dose not overheat wile moving then it is not your thermo stat period.
